Using the whole cell immobilized glucose isomerase which was prepared in the previous work (Korean J. Food Sci. & Technol., 11(3), 192 (1979), the specific activity of the immobilized enzyme was 48.1 units in the batch reaction system and 114 units in the continuous reaction system per g of matrix, respectively. In the continuous reactor the voidity was 0.36, which was suitable for the packed bed reactor. This immobilized enzyme showed a good operational stability of 115 days of half life which was sufficient for the continuous operation. The experimental result showed that 55 % of the substrate was converted to the product in the packed bed reactor. The productivity was dependent on the flow rate, column geometry, enzyme loading, and substrate concentration. An intrapaticle diffusion was observed by the effectiveness factor of 0.75 and interparticle diffusion by the decrease of Km' with increasing the superficial velocity.

Database integration has been recognized as a critical issue for effective logistics service in logistics environment. However, research related to effective methodology for this have been little studied, and also, prominent achievements have yet to be suggested. The aim of this paper is to present a quantitative methodology for the identification of conflict that is a representative problem on database integration. To achieve this aim, we suggested a quantitative methodology that can efficiently fine troubles such as name conflicts when schema integration, based on the level of semantic similarity between attributes and entities. And, in order to measure these semantic similarities, we used a thesaurus dictionary that proposed previous research. Finally, we presented effectiveness of the proposed methodology through some typical examples.

With the advances in multimedia databases on the World Wide Web, it becomes more important to provide users with the search capability of distributed multimedia data. While there have been many studies about the database selection and the collection fusion for text databases. The multimedia databases on the Web have autonomous and heterogeneous properties and they use mainly the content based retrieval. The collection fusion problem of multimedia databases is concerned with the merging of results retrieved by content based retrieval from heterogeneous multimedia databases on the Web. This problem is crucial for the search in distributed multimedia databases, however, it has not been studied yet. This paper provides novel algorithms for processing the collection fusion of heterogeneous multimedia databases on the Web. We propose two heuristic algorithms for estimating the number of objects to be retrieved from local databases and an algorithm using the linear regression. Extensive experiments show the effectiveness and efficiency of these algorithms. These algorithms can provide the basis for the distributed content based retrieval algorithms for multimedia databases on the Web.

Pedestrian safety was recently highlighted with a yellow carpet, a yellow-colored pavement material prepared for children waiting for signals for pedestrian crossing, without validation of its efficiency in practice. It was a promising device likely to assist highway safety by stimulating pedestrian to step on the yellow-colored area; it was generally called nudge effects. This paper delivers a study conducted to check the effectiveness of yellow carpet in three different aspects in vehicle driver's perspective by applying the newly introduced information technology (IT) service: Visual Attention Software (VAS). It was assumed that VAS developed by 3M in the United States should be able explain the Korean drivers' visual reaction behaviors since technology embedded in VAS was developed based on and proved by other various international countries and continents in the world. A set of pictures was taken at thirteen different field sites in seven school zone areas in the Seoul metropolitan area before and after the installation of a yellow carpet, respectively. Sets of those pictures were analyzed with VAS, and the results were compared based on the selective safety measures: the likely focusing on standing pedestrians (waiting for a pedestrian's green signal time) affected by its background (yellow-colored pavement) contrasting him or her. The test results from a set of before-and-after comparison analyses showed that the placement of yellow carpet would (1) increase 71% of driver's visual attention on pedestrian crossing areas and (2) change the sequential order of visual attention on that area 2.4 steps ahead. The findings would enhance deployment of such promising efficiency and thus increase children safety in pedestrian crossing. The result was promising to highlight the way to support the changes in conservative traffic safety engineering field by applying the advanced IT services, while much robust research was recommended to overcome the limitation of simplification of this study.

E-Government service is national project that is necessary for international competitiveness, openness of government and effectiveness of governmental work process. E-Government security is very important because it treats data has relatively high sensitivity. But, until now, the development point of E-Government service has been limited to only it's contents and infrastructure based on web without consideration of E-Government security. Lately research for E-Government security has been studied by some advanced country of E-Government service, but it is insufficient. To construct E-Government security based on web Infra, first of all, analysis of web service security technology is needed to precede. And then research for appling the technology to E-Government service are required. We propose secure E-Government service scenario with web service security technology based on development stages of E-Government service. We also suggest overall view and secure scenario of E-Government service in Integrated Computing Environment.

Background: Traction has often been utilized to treat patients with a herniated lumbar disc. Currently, the most advanced type of traction therapy is non-surgical spinal decompression. Therefore, this study was conducted to evaluate the effectiveness of decompression therapy in patients with a herniated lumbar disc based on clinical findings and symptoms. Methods: Sixty patients with herniated lumbar discs were included in this study. The patients were randomly divided into two groups, a decompression group (n = 30) and a traction group (n = 30). To evaluate the impact of decompression and traction therapy on the herniated disc, the clinical symptoms for each group were evaluated prior to and after treatment using the visual analogue scale (VAS), straight leg raising (SLR), the herniation index, and the disc height. Results: The VAS score was significantly lower in the decompression group ($2.0{\pm}0.2$) than the traction group ($3.9{\pm}0.2$) following treatment. In addition, the SLR angle was significantly higher in the decompression group ($79{\pm}1.5$) than the traction group ($63.3{\pm}1.9$). The herniation index was significantly lower in the decompression group ($217.6{\pm}19.1$) than the traction group ($259.5{\pm}16.4$). Finally, the disc height was not significant differences between pre-treatment and follow-up in two groups. Conclusions: The results of this study suggest that decompression therapy for the treatment of patients suffering from a herniated lumbar disc has an effect on the pain, SLR, and herniation indices, not disc heights.
